+Subject: [PATCH 10/16] cmd: load: add load command for memory mapped
+
+cp.b is used a lot as a way to load binaries to memory and execute
+them, however we may need to integrate this with the efi subsystem to
+set it up as a bootdev.
+
+So, introduce a loadm command that will be consistent with the other
+loadX commands and will call the efi API's.
+
+ex: loadm $kernel_addr $kernel_addr_r $kernel_size
+
+with this a kernel with CONFIG_EFI_STUB enabled will be loaded and
+then subsequently booted with bootefi command.

+Subject: [PATCH 01/23] usb: isp1760: fix strict typechecking
+
+There are a lot of pre-existing typechecking warnings around the
+access and assign of elements of ptd structure of __dw type.
+
+sparse: warning: invalid assignment: |=
+sparse:    left side has type restricted __dw
+sparse:    right side has type unsigned int
+
+or
+
+warning: restricted __dw degrades to integer
+
+or
+
+sparse: warning: incorrect type in assignment (different base types)
+sparse:    expected restricted __dw [usertype] dw4
+sparse:    got unsigned int [assigned] [usertype] usof
+
+To handle this, annotate conversions along the {TO,FROM}_DW* macros
+and some assignments and function arguments.
+
+This clean up completely all sparse warnings for this driver.

+
+There is already a binding to describe the dual role mode (dr_mode),
+use that instead of defining a new one (port1-otg).
+
+Update driver code and devicetree files that use that port1-otg
+binding.

+
+The ARM DEN0098 document describe an SMCCC based firmware service to

+
+Add a (dummy) call to probe functions implemented in each architecture

+Subject: [PATCH] arm64: smccc: Add support for SMCCCv1.2 extended input/output
+ registers
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+SMCCC v1.2 allows x8-x17 to be used as parameter registers and x4—x17
+to be used as result registers in SMC64/HVC64. Arm Firmware Framework
+for Armv8-A specification makes use of x0-x7 as parameter and result
+registers. There are other users like Hyper-V who intend to use beyond
+x0-x7 as well.
+
+Current SMCCC interface in the kernel just use x0-x7 as parameter and
+x0-x3 as result registers as required by SMCCCv1.0. Let us add new
+interface to support this extended set of input/output registers namely
+x0-x17 as both parameter and result registers.

+Subject: [PATCH] firmware: arm_ffa: Add initial FFA bus support for device
+ enumeration
+
+The Arm FF for Armv8-A specification has concept of endpoints or
+partitions. In the Normal world, a partition could be a VM when
+the Virtualization extension is enabled or the kernel itself.
+
+In order to handle multiple partitions, we can create a FFA device for
+each such partition on a dedicated FFA bus. Similarly, different drivers
+requiring FFA transport can be registered on the same bus. We can match
+the device and drivers using UUID. This is mostly for the in-kernel
+users with FFA drivers.

+
+There are requests to keep the transport separate in order to allow
+other possible transports like virtio. So let us keep the SMCCC transport
+specific routines abstracted.
+
+It is kept simple for now. Once we add another transport, we can develop
+better abstraction.

+Subject: [PATCH] firmware: arm_ffa: Setup in-kernel users of FFA partitions
+
+Parse the FFA nodes from the device-tree and register all the partitions
+whose services will be used in the kernel.
+
+In order to also enable in-kernel users of FFA interface, let us add
+simple set of operations for such devices.
+
+The in-kernel users are registered without the character device interface.

+ overflow
+
+The ffa_linux_errmap buffer access index is supposed to range from 0-8
+but it ranges from 1-9 instead. It reads one element out of bounds. It
+also changes the success into -EINVAL though ffa_to_linux_errno is never
+used in case of success, it is expected to work for success case too.
+
+It is slightly confusing code as the negative of the error code
+is used as index to the buffer. Fix it by negating it at the start and
+make it more readable.

+
+When polling for a setup or clear of a register field we were sleeping
+in atomic context but using a very tight sleep interval.
+
+Since the use cases for this poll mechanism are only in setup and
+stop paths, and in practice this poll is not used most of the times
+but needs to be there to comply to hardware setup times, remove the
+sleep time and make the poll loop tighter.

+Subject: [PATCH 19/23] usb: isp1760: fix memory pool initialization
+
+The loops to setup the memory pool were skipping some
+blocks, that was not visible on the ISP1763 because it has
+fewer blocks than the ISP1761. But won testing on that IP
+from the family that would be an issue.

+
+The set/clear of the otg control values is done writing to
+two different 16bit registers, however we setup the regmap
+width for isp1760/61 to 32bit value bits.
+
+So, just access the clear register address (0x376)as the high
+part of the otg control register set (0x374), and write the
+values in one go to make sure they get clear/set.

Peter Hoyes	36e43a3a21	runfvp: Ensure new process group is in the foreground When a new process group is created, it is launched in the background and any attempt to access the session terminal triggers a SIGTTIN (for stdin) or SIGTTOU (for stdout) signal. These are ignored in an interactive shell, but the default signal behavior in a new job is to send a SIGTSTP to the whole process group. This causes runfvp to hang when executed via a subprocess when stdin is accessed. After creating a new process group, use tcsetpgrp to make the new group the foreground process for the terminal associated with stdin/stdout, but only if stdin is a tty. The documentation for tcsetgrp states that tcsetpgrp itself raises a SIGTTOU signal, so set this signal to SIG_IGN.

Ross Burton	ba00c6d905	CI: enable testimage for fvp-base Inherit fvpboot so that the FVP binary is fetched and configuration generated. Configure the FVP to forward host port 8022 to port 22 locally, and tell testimage to SSH to localhost:8022. This has the limitation that only one testimage can run per machine, but this will be removed shortly. Disable the parselogs test case, as there are some harmless warnings in the dmesg which cause it to fail. Currently meta-arm can't extend the whitelist of ignorable warnings. The FVP binaries are x86-64 only, so tag the job appropriately. Signed-off-by: Ross Burton <ross.burton@arm.com> Signed-off-by: Jon Mason <jon.mason@arm.com>	2021-10-18 13:45:29 -04:00
